We look at the division of 13839373 by 320 
We want to divide 13839373 by 320.

Step 1:
When dividing 1 by 320, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 320

Moving on to step 2:
320 goes into 13 0 times with a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Include the next digit (8) from the dividend after 13, then repeat: 138 / 320

On to step 3:
138 divided by 320 is 0 with a remainder of 138.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 138 leaves us with 138.
Append the next digit (3) from the dividend to 138 and continue with: 1383 / 320

Step 4:
When dividing 1383 by 320, we get 4 with a remainder of 103.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 1280 from 1383 and we're left with 103.
Bring next digit (9) of the dividend behind the 103 and repeat the process: 1039 / 320

Moving on to step 5:
When dividing 1039 by 320, we get 3 with a remainder of 79.
Use 3 as the next digit of our solution. 
Result so far: 43.0
If we take 960 away from 1039, we end up with 79.
Take the next digit (3) from the dividend and append it to 79, then repeat: 793 / 320

On to step 6:
793 divided by 320 is 2 with a remainder of 153.
Write down 2 as next digit of the result. 
Result so far: 432.0
Deduct 640 from 793 and we're left with 153.
Bring next digit (7) of the dividend behind the 153 and repeat the process: 1537 / 320

Step 7:
1537 divided by 320 is 4 with a remainder of 257.
The next digit of our result is 4. 
Result so far: 4324.0
Subtracting 1280 from 1537 leaves us with 257.
Fetch the next digit (3) from the dividend, attach it to 257 and continue: 2573 / 320

Advancing to step 8:
2573 divided by 320 is 8 with a remainder of 13.
Record the quotient 8 as the next digit in the result. 
Result so far: 43248.0
Subtracting 2560 from 2573 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 9:
When dividing 130 by 320, we get 0 with a remainder of 130.
Put 0 as the next digit of the answer. 
Result so far: 43248.0
Subtracting 0 from 130 leaves us with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Moving on to step 10:
320 goes into 1300 4 times with a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 43248.04
If we subtract 1280 from 1300, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 11:
If we divide 200 by 320, we get 0 and a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 43248.04
If we take 0 away from 200, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 12:
If we divide 2000 by 320, we get 6 and a remainder of 80.
The next digit of our result is 6. 
Result so far: 43248.0406
Deduct 1920 from 2000 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 13:
320 can be fit into 800 2 times, resulting in a remainder of 160.
The number 2 becomes the next digit in our result. 
Result so far: 43248.04062
Subtract 640 from 800 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 14:
320 can be fit into 1600 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 43248.040625
If we subtract 1600 from 1600, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 15:
When dividing 0 by 320, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 43248.040625
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 16:
320 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 43248.040625
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 43248.040625, with a leftover of 0.0.
